Powerful Web Applications

What is Ruby and Rails ?

Many programmers are engaged in the time-consuming and monotonous process of repeating certain code in different places while developing a web application. The creator of Rails, David Heinemeier Hansson, found a great solution to this problem. He used Ruby development to put the most commonly repeated parts of the code into a framework to further use it for other applications. That’s how Rails was created. Now a day Ruby on Rails web development is independent and quickly growing infrastructure, including local departments such as Ruby on Rails Canada.

Rails is an open source framework used for web applications development that can automate a huge part of the process. Thus, Rails is not a programming language, it’s a set of standard libraries and methods (created using Ruby programming) that are taken as the basis for a future application. This framework when deployed makes the job of Ruby programmers simpler as it lessens the amount of code writing. Shorter program code means fewer bugs and easier maintenance. Besides it offers an excellent productivity and time-savings. You can perform the same amount of work with the help of Rails at least several times quicker than making it with Java, without sacrificing the quality of the final product. Thus, one of the main reasons to use Rails is to save plenty of time while creating database-backed applications. The secret of Ruby on Rails programming success is hidden in its main principles (each Ruby on Rails programmer should know and use them):

• Convention over configuration, which means that only unconventional parts of an application code need to be written and specified. Otherwise a programmer just needs to reuse an existing framework.
• Don't Repeat Yourself that asserts that all information should be placed in a single location to ensure an unambiguous point of reference, avoiding bugs and the necessity to rewrite anything over again.

Rails development framework is based on Model-View-Controller design, which basically splits the entire application into three parts or layers: Model, View and Controller.

• Model deals with the data model of the application.
• View is about the interface of the application or the way the data model is presented. We can say that this layer determines how the whole application will be shown to the user.
• Controller section of the MVC model is responsible for the application’s reaction to different events which are associated with it, or simply has the entire control over the application.

This division of layers, for example, helps the programmer to modify the information on the site without thus impacting its interface and vice versa.

In general, the fastness and simplicity of this framework provides both satisfaction for customers who get their projects cheap and on time and pleasant development experience for programmers.
